Abstract
The relationship between the concepts of Psychopathy (as conceptualised by a four-facet model of the Psychopathy Checklist – PCL-R; Hare, R.D. (2003). The Hare Psychopathy Checklist – Revised (PCL-R) (2nd ed.). Toronto: Multi-Health Systems) and the biopsychosocial model of normal personality (the Temperament and Character Inventory, – TCI; Cloninger, C.R., Przybeck, T.R., Svrakic, D.M., & Wetzel, R.D. (1994). The temperament and character inventory (TCI): A guide to its development and use. Washington University, St Louis, MI: Centre for Psychobiology of Personality) was explored in a sample (N = 121) of personality disordered, serious and repeat offenders. High total PCL-R scores were associated with high Novelty Seeking and low Harm Avoidance alongside the characteristic of low cooperativeness. At a facet level, Facet 1 (Interpersonal) was associated with low Harm Avoidance, Facet 2 (Affective) with low Reward Dependence and Facets 3 (Lifestyle) and 4 (Antisocial), with both high Novelty Seeking and low Co-operativeness. The results show that the different facets of psychopathy are related to different personality constructs as defined by the biopsychosocial model, which in turn may suggest different treatment and management regimes.
